Joomla!1.5 is not totally stable yet. The latest is, I believe, a Release Candidate 4. But I honestly believe there is still some work to be done with the core SEF, because many people are finding it buggy. If this problem is not solved by the developers, many plugins and components will have problems. So, from that point of view, it would be safer to work with the 1.0.x series.

On the other hand, Joomla! 1.5 is "the future" and a very promising product.

We'll have to wait and see ... For the moment, as I understand, it seems that it only uses Joomla! registration.

In one of my sites, I am using Joomla! 1.013 + SMF. The bridge allows me to choose what registration system I prefer to use, Joomla!'s own or SMF.So, I deduce that this new bridge could, hypothetically, use a similar approach?

James, are you coding in PHP or in Perl? And, will the bridge use Joomla!'s database to store members' details?I am not a developer or a programmer, but just curious. What I COULD do is translate your bridge into Spanish if you wished.
